[0016] The present invention has the following beneficial effects:

[0017] (1) The raw material grinding equipment for the production of building mortar is provided with a grinding roller, a first electromagnet, a connecting plate, a limiter and a second electromagnet. The second electromagnet is energized to fix the limiter. When the rotating rod rotates, the rotating shaft can be rotated by the gear and the gear ring, and then the connecting plate and the cutting knife are extended by centrifugal force, so that the raw materials can be cut during the mixing stage. After that, the first electromagnet is energized to fix the connecting plate, and the second electromagnet is de-energized. Under the action of centrifugal force, the grinding roller moves in the direction away from the rotating rod, and the grinding ring squeezes and grinds the raw materials away to crush them.

The raw materials cut by the cutting knife are stirred by the shovel plate on the screen plate for sufficient mixing. Before entering the grinding stage, the third electromagnet is powered off. Under the action of the friction between the screen plate and the shovel plate, the shovel plate rotates around the fixed rod, and under the action of the thread, the sealing part moves to block the material trough. In the subsequent grinding stage, the shovel plate can scoop up the raw materials, and then the raw materials in a suspended state are squeezed by the grinding roller and the grinding ring, and then crushed.

[0019] (3) The raw material grinding equipment for the production of building mortar uses fan blades, filter bags and fixed frames. During the mixing stage, the fan blades blow air into the grinding box, which can blow up the raw materials to a certain extent, making it easier to cut and mix. During the grinding stage, the fan blades are in the suction state, and the ground materials will pass through the sieve plate into the interior of the filter bag under the action of wind and be collected by the filter bag.

[0033] See also Figures 1-9 The embodiment of the present invention provides a technical solution: a raw material grinding device for producing building mortar, comprising a grinding box 1 having an air outlet and an air inlet, a rotating rod 2 being provided on the top of the grinding box 1 via a driver, one end of the rotating rod 2 movably passing through the grinding box 1, a grinding component being provided on the surface of the rotating rod 2 via a mounting frame 3, and a grinding ring 4 that cooperates with the grinding component being fixedly connected to the interior of the grinding box 1;

[0034] The surface of the mounting frame 3 is provided with a shoveling assembly for shoveling raw materials, the interior of the grinding box 1 is provided with a collecting component for collecting materials, the interior of the grinding box 1 is fixedly connected with a connecting spring 5, and one end of the connecting spring 5 is fixedly connected with a screen plate 6.

[0035] Specifically, the grinding components include a limiter 7, a rotating shaft 8, a grinding roller 9 and a return spring 10. The mounting frame 3 is fixedly sleeved on the surface of the rotating rod 2. One end of the limiter 7 movably passes through the mounting frame 3. One end of the return spring 10 is fixedly connected to the surface of the limiter 7. The other end of the return spring 10 is fixedly connected to the surface of the mounting frame 3. The limiter 7 is movably sleeved on the surface of the rotating shaft 8. The grinding roller 9 is fixedly sleeved on the surface of the rotating shaft 8. The surface of the limiter 7 is fixedly connected to the limiting protrusion 11. A limiting groove 12 is provided on the surface of the mounting frame 3. The surface of the limiting protrusion 11 is movably connected to the inner side wall of the limiting groove 12. A placement groove 13 is provided on the surface of the grinding roller 9. The inner wall of the groove 13 is fixedly connected to the first electromagnet 14, and a connecting plate 15 is movably provided inside the placement groove 13. The surface of the connecting plate 15 is fixedly connected to the cutting knife 16, and the surface of the cutting knife 16 is movably connected to the inner wall of the placement groove 13. The surface of the mounting frame 3 is fixedly connected to the second electromagnet 17, and the surface of the second electromagnet 17 is movably connected to the surface of the limit member 7. The surface of the rotating shaft 8 is fixedly sleeved with a gear 18. The interior of the grinding box 1 is fixedly connected to a gear ring 19 through a support rod, and the gear 18 is engaged with the gear ring 19. The surface of the connecting plate 15 is fixedly connected to a buffer spring 20, and one end of the buffer spring 20 is fixedly connected to the inner wall of the placement groove 13.

[0036] In this embodiment, during the mixing stage, the first electromagnet 14 is not energized, and the second electromagnet 17 is energized to fix the limiter 7, thereby limiting the rotating shaft 8. In the initial stage of rotation of the rotating rod 2, its rotation speed is not large, and the gear 18 on the rotating shaft 8 rotates slowly under the action of the gear ring 19. As the rotation speed of the rotating rod 2 continues to increase, the rotation speed of the gear 18 gradually increases under the action of the gear ring 19, thereby increasing the rotation speed of the grinding roller 9. Since the connecting rod 23 and the cutting knife 16 thereon are movably connected to the inner wall of the placement groove 13, after the rotation speed of the grinding roller 9 continues to increase, the connecting plate 15 and the cutting knife 16 will continue to move in the direction away from the rotating shaft 8 under the action of centrifugal force, thereby causing the cutting knife 16 to extend to the outside of the placement groove 13, and the buffer spring 20 is continuously compressed. When the rotating rod 2 reaches the maximum speed, the cutting knife 16 is continuously compressed. The knife 16 extends to the maximum length. At this time, after the raw material is fed into the feed port of the grinding box 1, the raw material will be cut by the cutting knife 16 when it moves from top to bottom, so that the particles of the raw material are further reduced. In the grinding stage, the rotation direction of the rotating rod 2 is opposite to the rotation direction in the mixing stage, and the first electromagnet 14 is energized and the second electromagnet 17 is de-energized. The first electromagnet 14 is energized to fix the connecting plate 15, thereby preventing the cutting knife 16 from moving during the grinding stage. In the grinding stage, the rotation speed of the rotating rod 2 also gradually increases. Under the action of centrifugal force, the grinding roller 9 will contact the grinding ring 4, crush the raw material, and then crush the raw material. In the process of the grinding roller 9 moving away from the rotating rod 2, the reset spring 10 is compressed, and the limit member 7 will move stably under the action of the limit protrusion 11 and the limit groove 12, so that the rotating shaft 8 can move stably.

[0037] Specifically, the shoveling assembly includes a connecting frame 21, a sleeve 22, a connecting rod 23, a third electromagnet 24 and a movable part 25. The connecting frame 21 is fixedly connected to the surface of the mounting frame 3, the sleeve 22 is fixedly connected to the surface of the connecting frame 21, the surface of the movable part 25 is movably connected to the inner wall of the sleeve 22, the third electromagnet 24 is fixedly connected to the inside of the sleeve 22, the surface of the third electromagnet 24 is movably connected to the surface of the movable part 25, the surface of the movable part 25 is fixedly connected to the limit spring 26, one end of the limit spring 26 is fixedly connected to the sleeve 22, and the connecting rod 23 is fixedly connected to the surface of the movable part 25. One end of the connecting rod 23 is movably connected to the movable part 25 through a connecting shaft, and the other end of the connecting rod 23 is movably provided with a shovel plate 27 through a fixed shaft. The shovel plate 27 is movably connected to the connecting frame 21 through a fixed rod 28. The surface of the shovel plate 27 is movably connected to the surface of the screen plate 6. The fixed rod 28 is fixedly connected to the surface of the connecting frame 21. The surface of the fixed rod 28 is provided with a thread. The shovel plate 27 is movably sleeved on the surface of the fixed rod 28. A material trough 29 is provided on the surface of the shovel plate 27. The interior of the material trough 29 is movably connected with a sealing groove part 30, and the sealing groove part 30 is threadedly sleeved on the surface of the fixed rod 28.

[0038] In this embodiment, during the mixing stage, the material trough 29 on the shovel plate 27 is open, and the sealing member 30 is hidden inside the material trough 29. The material trough 29 can allow the raw materials to pass through during the mixing process, thereby allowing the raw materials to be in a flowing state. After the preliminary mixing by the cutting knife 16, the different raw materials are further mixed to make the raw materials mixed evenly, and there is no need to mix them again after the grinding is completed. In the final stage of mixing, the third electromagnet 24 is powered off, and under the reset action of the limit spring 26, the movable part 25 tends to move downward. Under the action of the friction between the screen plate 6 and the shovel plate 27, the shovel plate 27 will rotate around the central axis of the fixed rod 28, the movable part 25 moves downward, the connecting rod 23 tilts, and during the rotation of the shovel plate 27, the sealing member 30 will move, thereby causing the sealing member 30 to close the material trough 29, and then enter the grinding stage. Since the shovel plate 27 is tilted at this time, the raw materials on the screen plate 6 can be scooped up, thereby facilitating the grinding roller 9 to crush the raw materials.

[0039] Specifically, the collecting component includes a fixing frame 31 and a filter bag 32. The filter bag 32 is fixedly connected to the surface of the fixing frame 31. The fixing frame 31 is fixedly connected to the grinding box 1 by screws. A sealing ring 33 is fixedly connected to the inside of the grinding box 1. The surface of the sealing ring 33 is movably connected to the surface of the filter bag 32. A fan blade 34 is fixedly sleeved on the surface of the rotating rod 2. A filter screen 35 is provided at the air inlet of the grinding box 1. The air outlet and air inlet of the grinding box 1 are respectively fixedly connected to the two ends of the ventilation pipe 36.

[0040] In this embodiment, during the mixing stage, the fan blades 34 will rotate with the rotating rod 2. At this time, the fan blades 34 blow air into the interior of the grinding box 1, blowing up the raw materials above the sieve plate 6, so that the cutting knife 16 can cut the raw materials again, and it is also convenient for the shovel plate 27 to mix the materials. Under the action of wind, the sieve plate 6 is in a ventilation state, which can prevent the raw materials from clogging the sieve holes. The filter screen 35 installed at the air inlet on the top of the grinding box 1 can prevent the raw materials from entering the interior of the ventilation pipe 36. In the grinding stage, the rotating rod 2 rotates in the opposite direction, and the fan blades 34 are in a suction state, which can extract the air inside the grinding box 1 and send it to the interior of the ventilation pipe 36, thereby making the bottom of the grinding box 1 in a negative pressure state. The dust generated by grinding can pass through the sieve plate 6 under the action of wind and enter the interior of the filter bag 32. Under the action of the filter bag 32, the ground material is collected. After the grinding is completed, the screws can be removed, so that the fixing frame 31 can be taken out, which is convenient for centralized processing of the material inside the filter bag 32.

[0041] When in use, the driver drives the rotating rod 2 to rotate, and the rotating rod 2 drives the mounting bracket 3 to rotate, and the mounting bracket 3 drives the rotating shaft 8 to move through the limiter 7. The rotating shaft 8 is movably connected to the limiter 7. When the rotating shaft 8 rotates around the central axis of the rotating rod 2, the gear 18 and the gear ring 19 on it will be relatively displaced. Since the gear ring 19 is fixed, the gear 18 will roll on the gear ring 19, and then the rotating shaft 8 will rotate around its own central axis, thereby rotating the grinding roller 9. At this time, the second electromagnet 17 is energized, so the limiter 7 is fixed. As the rotation speed of the rotating rod 2 gradually increases, the rotation speed of the grinding roller 9 will also increase. The connecting plate 15 and the cutting knife 16 thereon are movably connected to the inner wall of the placement groove 13. As the rotation speed increases, the connecting plate 15 and the cutting knife 16 thereon are movably connected to the inner wall of the placement groove 13. The centrifugal force of the knife 16 gradually increases, the connecting plate 15 moves in the direction away from the first electromagnet 14, the cutting knife 16 gradually extends to the outside of the grinding roller 9, the buffer spring 20 is compressed, and the mounting frame 3 drives the shovel plate 27 to move through the connecting frame 21. At this time, the shovel plate 27 is in a vertical state, the material trough 29 is in an open state, and the third electromagnet 24 is energized to fix the movable part 25, thereby preventing the movable part 25 from moving during the rotation, causing the shovel plate 27 to tilt. At this time, the limit spring 26 is in a compressed state. When the speed of the rotating rod 2 reaches the maximum, the buffer spring 20 is no longer compressed, and the cutting knife 16 reaches its maximum extension length. At this time, different raw materials are quantitatively fed into the interior of the grinding box 1 through the feed port on the top of the grinding box 1, and the raw materials are fed from the top to the bottom. The raw materials fall down and are hit by the high-speed rotating grinding roller 9, which can make the different raw materials preliminarily mixed, and the cutting blade 16 will also cut the raw materials to reduce the volume of the raw materials again. After being cut by multiple sets of cutting blades 16, the raw materials fall to the position of the shovel plate 27, and the shovel plate 27 can continue to stir the raw materials. At this time, the material trough 29 on the shovel plate 27 is in an open state, allowing the raw materials to pass through. Therefore, the shovel plate 27 at this time is equivalent to a mesh plate that can stir the raw materials, so that the raw materials are continuously mixed. The connecting spring 5 fixedly connected to the lower surface of the sieve plate 6 is in a compressed state at this time, so the sieve plate 6 has a tendency to move upward, and can then closely contact the surface of the shovel plate 27. When the rotating rod 2 rotates, it will also drive the fan blade 34 to rotate. When the fan blades 34 are in the state of blowing air into the grinding box 1, the wind force can be used to float the lighter raw materials while the shovel plate 27 is stirring, thereby further enhancing the mixing effect, and the sieve plate 6 can be dredged by the wind force to prevent it from being blocked. The filter screen 35 on the top of the grinding box 1 can prevent the raw materials from entering the interior of the ventilation pipe 36. The ventilation pipe 36 is used to circulate air. After stirring for a period of time, the rotation speed of the rotating rod 2 gradually decreases. When the rotation speed of the rotating rod 2 is reduced to a specified size, the third electromagnet 24 is powered off. The third electromagnet 24 is fixedly connected to the inside of the sleeve 22. After the movable part 25 loses its fixation, it moves downward under the resetting action of the limit spring 26. The sleeve 22 can guide and limit its movement, thereby making its movement stable.At this time, the rotating rod 2 still has a certain rotation speed. Under the action of the screen plate 6 and the raw material, the shovel plate 27 will rotate around the fixed rod 28. The connection between the shovel plate 27 and the screen plate 6 is opposite to the rotation direction of the rotating rod 2, and the connecting rod 23 is tilted. This movement is similar to the movement of the connecting rod. Since the screen plate 6 loses its extrusion force at this time, the screen plate 6 will move upward for a distance under the action of the connecting spring 5. Under the action of the gravity of the raw material, the connecting spring 5 cannot be completely restored. Therefore, the screen plate 6 always has a tendency to move upward. At this time, the limit spring 26 is in a basically restored state. During the rotation of 6, the sealing member 30 is driven to rotate through the material trough 29. The sealing member 30 is threadedly connected to the fixed rod 28. Under the action of the threads on the surface of the fixed rod 28, the sealing member 30 moves toward the direction close to the rotating rod 2, thereby blocking the sealing member 30. The surface of the sealing member 30 can be set to a smooth curved surface to facilitate blocking and prevent it from being blocked by the raw material and unable to move. As the speed of the rotating rod 2 gradually decreases, the buffer spring 20 gradually recovers, and the connecting plate 15 drives the cutting knife 16 to gradually retract into the interior of the grinding roller 9, and finally the rotating rod 2 stops rotating;

[0042] When the rotating rod 2 stops rotating, the first electromagnet 14 is energized to fix the connecting plate 15, and the second electromagnet 17 is de-energized at the same time, and the limit member 7 loses its fixation. After that, the driver reverses the rotating rod 2, and the rotating rod 2 drives the rotating shaft 8 to rotate around the central axis of the rotating rod 2 through the mounting bracket 3. In the early stage of the rotation of the rotating rod 2, the speed is not large, and the gear 18 is still engaged with the gear ring 19. The rotating shaft 8 drives the grinding roller 9 to rotate. The shovel plate 27 is in an inclined state at this time and can shovel the raw materials. When the speed of the rotating rod 2 gradually increases, the centrifugal force of the rotating shaft 8 and the grinding roller 9 gradually increases, and begins to move in the direction away from the rotating rod 2. The reset spring 10 is compressed, and the limit member 7 moves synchronously with the rotating shaft 8. In the process of encountering, the limiting protrusion 11 cooperates with the limiting groove 12 to limit the limiting member 7 The movement of the rotating rod 2 is guided and limited, and then it can be guided and limited with the movement of the rotating shaft 8 and the grinding roller 9. The shovel plate 27 can shovel the raw materials. When the speed of the rotating rod 2 reaches the maximum, the surface of the grinding roller 9 will contact the surface of the grinding ring 4, and under the action of centrifugal force, the grinding roller 9 will squeeze the grinding ring 4, and then the grinding roller 9 can squeeze the raw materials scooped up by the shovel plate 27. Under the action of friction, the grinding roller 9 rolls on the grinding ring 4 to crush the raw materials. Under the action of strong centrifugal force, the grinding roller 9 crushes the raw materials, and in this process, the shovel plate 27 will also continuously stir the raw materials. At the same time, under the action of the rotating rod 2, the fan blades 34 fixed thereon rotate. At this time, the fan blades 34 are in the state of exhausting air, which The air is drawn to the ventilation pipe 36, thereby forming a negative pressure at the bottom of the grinding box 1. The dust formed by the crushing inside the grinding box 1 passes through the sieve plate 6 under the action of wind and then reaches the bottom of the grinding box 1, and is filtered through the filter bag 32, so that the ground material can be collected in the inside of the filter bag 32. Under the stirring action of the shovel plate 27, the raw material will not always be in contact with the sieve plate 6, which can facilitate the dust to pass through the sieve plate 6. As the grinding continues, the total mass of the raw material continues to decrease. At this time, the pressure on the sieve plate 6 is reduced, so that the connecting spring 5 can start to recover, and thus the sieve plate 6 can always be in contact with the bottom of the shovel plate 27. The elastic coefficient of the connecting spring 5 is greater than the elastic coefficient of the limit spring 26, so that the shovel plate 27 will move upward on the sieve plate 6. When the movable part 25 rotates to a certain extent under the action of the movement, the limit spring 26 will be stretched to a certain extent, and the movable part 25 will tend to move toward the third electromagnet 24, so that the shovel plate 27 can have a tendency to suppress the upward movement of the sieve plate 6 by making the connecting rod 23, so that the bottom of the shovel plate 27 can always be in contact with the sieve plate 6, and the shovel plate 27 can further enhance the effect of shoveling the material. Under the high-speed rotation of the rotating rod 2, the raw material will basically be in a suspended state, which is convenient for the grinding roller 9 to crush the raw material, and it is also convenient for the dust to pass through the sieve plate 6 under the action of wind to enter the filter bag 32 for collection. After the grinding is completed, the screws on the fixing frame 31 are removed, the filter bag 32 can be taken out, and the collected materials can be processed centrally.
